Looking for something low-key to do this evening? Well, look no further. About Sounds and Subsystence bring local DJs Atomly, Ken Meier and Matt Hellige to Wicker Park's very own Subterranean for an evening of abstract electronic music. Despite the location, the night should be surprisingly devoid of jukebox rock and hipster disco. No, honestly. And best of all, it's free. More details over in Slowdown, if you feel the need.
